What is 16.2 simplified (and 121 simplified to)

Cerrena [4.2K]

Answer:

16.2 = $\frac{81}{5}$ and 121 = $\frac{121}{1}$

Step-by-step explanation:

16.2 can be simplified to its fraction form, which is $\frac{81}{5}$

$16+\frac{2}{10} =\frac{81}{5}$ which is 16.2

121 is already simplified since it is a whole number, but its fraction form would be $\frac{121}{1}$

$121+\frac{0}{10} =121$ which is 121

If the diameter of a hockey rink is 250 ft what is the surface area of the sphere?

Lady bird [3.3K]

Answer:

62,500 pi

Step-by-step explanation:

diameter = radius + radius

d = 2r

r = d/2

A = 4pi r^2

= 4 pi (d/2)^2

= 4pi d^2/4

= 4pi* 250^2/4

= 4pi * 62,500/4

= 4pi * 15625

= 62,500 pi

One integer added to another integer gives a sum of 2. When the larger integer is subtracted from the smaller integer, the diffe

alexandr402 [8]

For this case we have the following variables, let:

x: The greater integer

y: The minor integer

We have to:

$x + y = 2 (1)\\y-x = -14 (2)$

Thus, we have a system of two equations with two unknowns. To solve, we follow the steps below:

Step 1:

We add both equations:

$x + y + y-x = 2-14\\2y = -12$

$y = \frac {-12} {2}\\y = -6$

Thus, the smallest integer is $y = -6$

Step 2:

We substitute "y" in any of the equations and clear x:

$x + y = 2\\x + (- 6) = 2\\x-6 = 2\\x = 2 + 6\\x = 8$

Thus, the largest integer is $x = 8$

So:

$8 + (- 6) = 8-6 = 2\\-6-8 = -14$

Anwer:

Integer minor, $y = -6$

Integer greater, $x = 8$
